COLLAPSIBLE HORN.

To aZZ whom it may concern:

Be itknown that I, LOUIS on VINEAU,a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented a certain new and useful Improvement in Collapsible Horns, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to improvements in horns which are used in connection with phonographs or megaphones, and relates specifically to those which may be collapsed in a manner such that they will not occupy agreat 'deal of space.

The invention further relates to certain means for holding a horn of this type in its extended position.

In the drawings, Figure l is a side elevation of the horn extended, being partly broken away to show the interior. Fig. 2 is a plan of the horn collapsed and contained within a suitable box. Fig. 3 is a side elevation of a portion of one of the sectional rods, and Fig. 4 is a section through the clamping-screw which secures the end of the rod.

The horn is made of any convenient number of sections, six being shown in the drawings. The largest section 0t is shown with the usual flaring end, and the smallest section a may be adapted to receive a mouthpiece or flexible tube. Between these sections are intermediate sections a each tapered and extending within the adjacent larger section and outside of the adjacent smaller section. Each of the sections are substantially the same height, so that the horn maybe collapsed and occupy no more space than that necessarily occupied by the largest section. When the horn is extended, as shown in Fig. 1, the taper of the sections prevents its pulling apart, and it is held in this position by suitable rods B, which are clamped to the extreme sections a and a of the horn by means of clamps or binding-posts 0?, which are secured to the extreme sect-ions of the horn.

To enable the rods B to occupy small compass, they are made sectional. They consist, as shown, of an intermediate tubular section b and a pair of solid end sections b. Each end section has an extension 12 adapted to extend into the bore of the section b, and has an abutting and limiting shoulder b O represents a square box, which is adapted to contain the collapsed horn. Within this box near its upper edge may be formed a small shelf or tray 0, adapted to contain the disconnected members of the rods B.

It will be seen that the horn which I have provided is neat in appearance when extended, has all the advantages of the usual one-piece horn, and may be collapsed into small and convenient space for carrying.

Having described my invention, I claim-- 1. A collapsible horn consisting of telescoping sections adapted to stand each within the next larger or be extended, and a rod secured to the extreme sections for holding the horn in its extended position, said rod being separable into sections, substantially as described.

2. A collapsible horn consisting of tapered telescoping sections adapted to stand each within the next larger or be extended, the taper of the sections preventing them pulling apart when extended, and a rod outside of the horn and parallel with it and secured to the extreme sections for holding the horn in its extended position, said rod being separable into sections, substantially as described.

3. A collapsible horn consisting of telescoping sections, binding-posts secured to the extreme sections, and a rod adapted to extend into and be clamped by said binding-posts for holding the horn extended, substantially as described.

at. A collapsible horn consisting of telescoping sections, clamps secured to the extreme sections, and a rod adapted to be held by said clamps for holding the horn extended, said rod being made sectional and comprising a tubular member, and removable extensions adapted to extend thereinto, substantially as described.

5. A collapsible horn consisting of telescoping sections, and a rod for holding the horn extended, said rod being made sectional and comprising a tubular member, and removable extensions adapted to extend thereinto, said extensions having shoulders abutting against the ends'of the tubular member and limiting insertion thereinto, substantially as described.

6. A collapsible horn consisting of a series treine sections, and a sectional rod adapted, when extended,to project into,and be clamped by said binding-posts, substantially as described.

In testimony whereof I hereunto al'lix my signature in the presence of two Witnesses.
